RIVETING DEVICE.

Application filed October 3, 1921. Serial No. 504,922.

To all whom it may concern:

Be it known that I, PETER D. MCNAUGH- TON, a subject of the King of England, residing in the city of Dighton and State of Michigan, have invented new and useful Improvements in Riveting Devices, of which the following is a specification, reference being had to the accompanying drawings.

This invention is a harness makers horse, and the object is to provide a simple, practical and efiicient device of this kind, conveniently adapted to the general purposes of a harness maker, and embodying a vise, rivet setter, tool box and other elements.

In the drawings:

Fig. 1 is a perspective view of the device.

Fig. 2 is a detail of the circular wedge cam of the rivet setting pin actuating lever, and showing also the rivet setting pin which passes through the margin of the work support and rides on this cam.

Fig. 3 is a detail of the arrangement of the vise locking screws.

In carrying out this invention, I provide a base block 1, mortised out at 2 and thus adapted to slide upon the edge of a bench. It is releasably secured to such bench or other support by means of the thumb-screw 8 passed through the lower arm of the block 1. The forward end of this lower arm is extended out to afford a bearing 9 for the vise 4, the shanks 5 of the jaws thereof being pivoted for vertical movement to the squared head 7 by means of a thumb screw 8 passed transversely through the said shanks and head; and the head 7 being in turn pivoted for horizontal rotation to the bearing 9 by means of another thumb screw 10 passed up through said bearing and into the head 7. The jaws 6 of the vise are opened or closed in usual form by means of the thumb screw 11 passed through the vise arms 12. The vise 4 may thus be locked in any relatively raised or lowered position by means of the screw 8, and in any horlzontal position by the screw 10. A work support 13 is mounted upon the upper arm of the block 1, and a tool box 14 may also be mounted on this base block. The work sup port 13 is extended out at one side to form a ledge 15, the forward end of which is supported and reinforced by the bolster 16. Immediately below this bolster 16 another bolster 17 is formed or mounted, being supported from the base block 1-. A rivet setting pin actuating lever 18, having a circular end 19 is pivotally mounted for horizontal movement between the bolsters 16 and 17, by passing a pin 20 down through the bol sters 16 and 17 and the center of the said circular end 19 of the lever 18. The under side of the circular end 19 is cut away on a slope, so as to form a wedge-shaped circular cam 21 around the under face of this circular end, near the periphery thereof, the slope of said cam commencing at a point opposite to the lever 18 and ending immediately back of said lever at its point of juncture with said circular end 19. Cooperating with this circular cam 21 is a stud 22 rigidly mounted on the bolster 17, whereby, as the lever 18 is moved to the left, or clockwise, the said circular end 19 of the lever is caused to rise vertically, riding upon the stud 22 and sliding upward on the pin 20. A hole 23 is pierced through the work support 13 and bolster 16 at a point preferably above the stud 22, and through this hole is slidingly mounted a steel rivet setting pin 24, the lower end of this pin riding upon the upper face of the circular and 19. Thus the pin 24 will be caused to rise as the lever 18 is moved clockwise. An overhanging arm or arbor 25 is mounted 0n the work sup-- port 13 and impends over the pin 24, and through this arm 25 is passed an adjusting screw 26 in immediate alignment with the pin 24.

The operation of the vise portion of the apparatus is obvious and nothing novel is claimed in respect thereof except the adjustable mounting of the vise. In the use of the rivet setting part of the apparatus, the ends of the straps to be riveted together are properly pierced with a hole, and a rivet inserted, head down; after which these ends are placed under the screw 26 which is turned down immediately upon the end of the rivet. The lever 18 is then moved to the left which causes the pin 24 to rise, thus splitting the rivet.

While I have herein described a certain specific method of constructing and assembling the elements of my invention, it is understood same may be varied in minor details, not departing from the spirit of my invention as defined in the appended claim.

I claim:

A riveting device, comprising, in combination, a base block provided with means for securing the same to a support, a work support mounted on top of said base block provided at its free edge with a portion extended over the base block and with an aperture adapted to receive a rivet setting pin, vertically spaced bolsters mounted on the base block beneath the free edge of the Work support, the upper bolster being in contact with the said free edge of said Work support, a rivet setting pin actuating lever ivoted for horizontal movement between said bolsters, the pivoted end of said lever being circular in form and having a Wedge shaped circular cam on its under face near the periphery of the circular end, a stud on the lower bolster cooperating With said Wedge shaped circular cain of the lever, a rivet setting pin slidable in the aperture in said Work support With its lower end riding upon thecircularrend of the lever, an arbor mounted on the Work support and extending oversaid rivet setting pin, and an adjustment screw passed vertically through said arbor and aligned with said rivet setting pin.
